Description

Technical Field

[0001] This utility model relates to the field of support and hanger technology, and in particular to an adjustable seismic support and hanger. Background Technology

[0002] With the continuous development of society and the continuous progress of science and technology, the technology related to supports and hangers is also constantly improving. Seismic supports and hangers are seismic support systems with seismic force as the main load. They are a type of seismic support measure designed to transmit the seismic forces generated by pipelines and equipment to the structure when encountering an earthquake of the design intensity.

[0003] The supports and hangers currently in use cannot be adjusted to adapt to actual usage conditions, resulting in significant limitations in their use and making them unsuitable for meeting diverse application needs. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the existing technology: the support and hanger currently used cannot be adaptively adjusted according to the actual use, which leads to great limitations in the use of the support and hanger, and cannot meet different use needs, which is not conducive to the use of the support and hanger. Therefore, an adjustable seismic support and hanger is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable seismic bracing system includes a mounting plate with multiple mounting holes. An annular block is fixedly connected to each mounting hole. Multiple slots arranged in a circular array are formed on each annular block. A threaded groove is formed on the lower inner wall of each slot. A support crossbar is fixedly connected to each slot. A threaded rod is inserted into one of the mounting holes. A rotating groove is formed at the upper end of the threaded rod. A round rod is inserted into the rotating groove. A bracket is fixedly connected to the upper end of the round rod. A T-shaped rotating shaft is connected to the bracket via a torsion spring. A fixing component is mounted on the T-shaped rotating shaft. Multiple through slots are formed on the T-shaped rotating shaft. Multiple locking blocks arranged in a circular array are fixedly connected to the bracket. One locking block has a circular groove. A circular hole is formed on the lower inner wall of the circular groove. A vertical rod is threadedly connected to the circular hole.

[0007] Preferably, a first annular piece and a second annular piece are fixedly connected to the vertical rod, the second annular piece is disposed below the locking block, and the lower end of the vertical rod is threadedly connected to the corresponding threaded groove.

[0008] Preferably, a nut is threaded onto the threaded rod, and an annular washer is provided between the nut and the lower surface of the mounting plate, the annular washer being sleeved on the outside of the threaded rod.

[0009] Preferably, the fixing component includes a rotating frame fixedly mounted on the T-shaped rotating shaft, a lower clamping seat fixedly connected to the rotating frame, and an upper clamping seat connected to the rotating frame via an electric push rod.

[0010] Preferably, both the lower clamping seat and the upper clamping seat are fixedly connected with shock-absorbing pads, and the shock-absorbing pads are made of rubber.

[0011] Preferably, the mounting plate has multiple fixing holes, which are arranged symmetrically.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] Manually rotate the vertical rod. As the vertical rod moves downward, the first annular piece moves downward within the circular groove until the upper end of the vertical rod disengages from the through groove. Then, the T-shaped rotating shaft and the bracket can rotate, causing the rotating frame to deflect back and forth, thus changing the angle of the rotating frame. Manually rotate the vertical rod upward until the lower end of the vertical rod disengages from the threaded groove. Then pull the vertical rod upward, and the second annular piece moves upward along with the corresponding lower surface of the locking block until all the locking blocks disengage from the slot. At this point, the upper end of the vertical rod inserts into the through groove. The bracket can then be rotated, and the circular rod rotates within the rotating groove, allowing the rotating frame to rotate around the circular rod as its axis. The angle of the rotating frame can be adjusted from another angle. The angle of the support can be adaptively adjusted according to actual usage, resulting in fewer limitations in its use and meeting various application requirements, thus facilitating the use of the support.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-5 An adjustable seismic bracing system includes a mounting plate 1 with multiple mounting holes 16. Each mounting hole 16 has a fixedly connected annular block 12. Each annular block 12 has multiple slots 14 arranged in a circular array. The lower inner wall of each slot 14 has a threaded groove 17. Each slot 14 has a fixedly connected supporting crossbar 15. A threaded rod 2 is inserted into one of the mounting holes 16. The upper end of the threaded rod 2 has a rotating groove, into which a round rod 20 is inserted. A bracket 5 is fixedly connected to the upper end of the bracket 5. A T-shaped rotating shaft 11 is connected to the bracket 5 via a torsion spring. A fixing component is installed on the T-shaped rotating shaft 11. Multiple through slots 22 are opened on the T-shaped rotating shaft 11. The multiple through slots 22 are arranged in a ring array. Multiple locking blocks 21 arranged in a ring array are fixedly connected to the bracket 5. One of the locking blocks 21 has a circular groove 18. A circular hole is opened on the lower inner wall of the circular groove 18. A vertical rod 6 is threaded into the circular hole. The diameter of the through slot 22 is 0.05 mm larger than the diameter of the vertical rod 6.

[0022] A first annular piece 13 and a second annular piece 19 are fixedly connected to the vertical rod 6. The outer surface of the part of the vertical rod 6 below the first annular piece 13 is provided with threads. The second annular piece 19 is located below the locking block 21. The lower end of the vertical rod 6 is threadedly connected to the corresponding threaded groove 17. The vertical rod 6 is manually rotated to move it upward until the lower end of the vertical rod 6 is disengaged from the threaded groove 17. Then, the vertical rod 6 is pulled upward, and the second annular piece 19 moves upward together with the lower surface of the corresponding locking block 21 until all the locking blocks 21 are disengaged from the slot 14. At the same time, the round rod 20 moves upward along the rotating groove with a circular cross-section. After that, the bracket 5 can rotate around the round rod 20 as the axis.

[0023] A nut 3 is threaded onto the threaded rod 2. An annular washer 4 is placed between the nut 3 and the lower surface of the mounting plate 1. The annular washer 4 is fitted onto the outside of the threaded rod 2. One end of the threaded rod 2 is inserted into the mounting hole 16. Then, the annular washer 4 is fitted onto the outside of the threaded rod 2 and fits against the lower surface of the mounting plate 1. The nut 3 is then rotated to make it threaded onto the threaded rod 2 until the end face of the nut 3 is tightly fitted against the lower surface of the annular washer 4. The threaded rod 2 and the mounting plate 1 are then firmly connected together. Depending on the actual use requirements, an appropriate number of threaded rods 2, brackets 5, and rotating frames 10 can be installed on the mounting plate 1.

[0024] The fixing assembly includes a rotating frame 10 fixedly mounted on a T-shaped rotating shaft 11. A lower clamping seat 7 is fixedly connected to the rotating frame 10. An upper clamping seat 9 is connected to the rotating frame 10 via an electric push rod 8. Shock-absorbing pads are fixedly connected to both the lower clamping seat 7 and the upper clamping seat 9. The shock-absorbing pads are made of rubber. One end of the pipe passes through the rotating frame 10, and the surface of the pipe is in close contact with the shock-absorbing pad on the lower clamping seat 7. The electric push rod 8 is fixedly connected to the rotating frame 10. The drive end of the electric push rod 8 is fixedly connected to the upper clamping seat 9. The electric push rod 8 drives the upper clamping seat 9 to move downward until the shock-absorbing pad on the upper clamping seat 9 is also in close contact with the pipe, thus clamping the pipe. The shock-absorbing pad can improve the shock absorption effect of the clamping seat. The mounting plate 1 has multiple fixing holes, which are symmetrically arranged. The fixing holes facilitate the connection of the mounting plate 1 with bolts to other components, so as to facilitate the installation of the mounting plate 1.

[0025] In the initial state, the lower end of the vertical rod 6 is threadedly connected to the threaded groove 17, and the upper end of the vertical rod 6 is inserted into the corresponding through groove 22. At this time, the first annular piece 13 is located inside the circular groove 18, and each locking block 21 is engaged in the corresponding slot 14. The lower surface of the locking block 21 is in contact with the upper surface of the corresponding supporting horizontal piece 15. When the vertical rod 6 is manually rotated, it will move vertically downwards during the threaded connection between the vertical rod 6 and the threaded groove 17. At the same time, the first annular piece 13 moves downwards in the circular groove 18 until the upper end of the vertical rod 6 is disengaged from the through groove 22. Then, the T-shaped rotating shaft 11 and the bracket 5 can be rotated, thereby causing the rotating frame 10 to deflect back and forth, which can change the angle of the rotating frame 10. Then, the vertical rod 6 is returned to the initial position, which can effectively prevent the rotating frame 10 from rotating arbitrarily. The vertical rod 6 can be manually rotated to move it upwards until the vertical rod 6... The lower end of the rod 6 disengages from the threaded groove 17, and then the vertical rod 6 is pulled upward. At the same time, the second annular piece 19 moves upward along with the lower surface of the corresponding locking block 21 until all the locking blocks 21 disengage from the slot 14. At this time, the upper end of the vertical rod 6 is inserted into the interior of the through groove 22. The depth of the through groove 22 is sufficient. At the same time, the round rod 20 moves upward along the rotating groove with a circular cross-section. Then the bracket 5 can be rotated. The round rod 20 rotates in the rotating groove, which allows the rotating frame 10 to rotate around the round rod 20 as the axis. The angle of the rotating frame 10 can be adjusted from another angle. Then the vertical rod 6 returns to the initial position, which prevents the rotating frame 10 from continuing to rotate. The angle of the support can be adjusted adaptively according to the actual use. The support has fewer limitations in use and can meet different use requirements, which is beneficial to the use of the support.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
